Description

Наиболее близким по технической сущности чвл чете   жепезосеребр ный материал дл  электрически контактов, содер + зщий 3-30 пас. % епеза, серебро остальноеThe closest in technical essence, including the silver-silver material for electrical contacts, containing + 3-30 pass. % ephesa, silver rest

Однако указанный материал имеет большое контэнтное сопротивление, чго вызывает нагрев контактов и тем самым уменьшает срок и службы,.However, this material has a large kontentnoy resistance, which causes heating of the contacts and thereby reduces the life and service.

Целью изобретени   вл етс  увеличение срока служба электрически ионтактовThe aim of the invention is to increase the service life of electrical contacts

Поставленна  цепь достигаетс  благодар  топу, что в челезосеребрчном матери- апе дл  электрически контактов, содержащем 3-30 пас % железа, а остальное-серебро , еще добавлено 0, мае,. /о цинкаThe delivered circuit is achieved thanks to the top that in the silver-silver material for electrical contacts containing 3-30 pass% iron, and the rest is silver, it was added on May 0. / o zinc

По причине нерастворимости мелела в серебре чтим материалы не могут быть изготовлены ппрометаплургичееким путем Изготовление материалов осуществл етс  по известной технологии порошковой металлургии При этом благопри тным оьазалось , что использованный + елезныи порошок не крупнее 32 ш м Благодар  этому добиваютс  очень равномерного распределени  частиц , кепезз в смеси и ЕО взэигюдействии с другими присадочными материалами получаетс  незначительное образование покровного сло  прм переь лго- чени Due to the insolubility of chalk in silver, we can’t prepare materials using the metallurgical method. The materials are manufactured using the well-known powder metallurgy technology. It was favorable to use the used + iron powder no larger than 32 cm. Thanks to this, a very uniform distribution of particles is achieved, and the creep in the mixture and EO, when interacting with other filler materials, an insignificant formation of the coating layer is obtained

С изготовленными Tai им образом материалами были проведены испытани  электрически переключений Нар ду с проверкой контактного сопротивлени  на моделирующем испытательном стенде была использована также серийна  защита дл With the materials made by Tai in his own way, electrical switching tests were carried out. In addition to checking the contact resistance on the modeling test bench, a serial protection was also used for
